【摘要】 将天然矿泉水或地下水水样蒸发浓缩后,于XDY—Ⅱ型原子荧光光度计上测定锡的荧光强度。此法操作简单、快速、灵敏度高、检出限低。其相对标准偏差为2.34％,最低检出限为0.49μg/L,锡的回收率为97％—104％。更多还原

【Abstract】 After natural mineral water and underground water samples are evaporated and concentrated, their fluorescence densities are tested in XDY—Ⅱ model atomic fluorescence spectrometry. This method is simple, rapid, and has high sensitivity and low detection limit which the RSD is 2.34％, the lowest detection limit is 0.49μg/L, and the recovery percent ranges from 97 to 104％.更多还原
